- Clarify which bits are for which chips. - Note that gen2 can't do interlaced directly (only via dvo tv chips). - Move the mask to the top to make it clearer how wide this field is. - Add defintions for all possible values. This patch doesn't change any code. v2: Paulo Zanoni pointed out that the pixel doubling modes do no longer exist on ivb.
